2. run 'python3 manage.py makemigrations' to create migrations for those changes
3. run 'python3 manage.py migrate' to apply those changes to the database

each view is responsible for doing one of two things: returning an HttpResponse object containing the content for the requested page, or raising an exception such as Http404.
